To all whom it may concern: Be it known that I, W LLIA A,'BRADEN, a citizen of the United, States, residing-at Chicago, 1n the county of. Cook and State of Illi-' nois, have invented certain newand useful Improvements in Track Constructions, of.v which the following is a specification.

My invention re ates to track construction. and particularly to that type wherein stifiening sections are employed beneath-and parallel to the rails. The invention has for its principal objects; the provision of improved and slmplified means for securing the rails and stiffening sections rigidly in their proper relative positions the provision of improved means for maintainingthe opposing rails in paralle 111 independent of the ties; and the provision of a simple and efiicient form of tie tocooperate with the track construction and assist in anchoring the rails to the road bed. Certain specific embodiments of the-inventlon are. illustrated in the accompanying drawings-,wherein 1 I F' re 1.is a transverse section through one orm of track construction, j; Figure-2 is atransverse section through a slightly modified-form of track construction, 'gure 3 is a section through the ties taken on the lines IlL-III of Figure 2, and shows the principal part; of-the track construction insideelevation, Figure 4 is'an enlarged detail crosssection through .one side of the'track construction,

Figure 5 is a side elevation of the structure shown in Figure 4, Figure 6 is a longitudinal section. of the securing. means onthe line VIVI of Figure '5, Figure 7 is a side elevation of the tieemployed with the rails shown-in section therel r fl I Figure '8 'isa longitudinal section taken through'the'tie of FiguI'e-7,-

The rails 1-1 and beams 21-20n eachside of the track are held securely" infi cede relation to each other by '60. means ,of opposing clamping members 4,

which clamping members as shown are shal'ped to fit: the, flanges of. the members 1 an '2, and are spaced along the track at short intervals as construction in fixed relationwith respect to clam 1 the members vided.v The rod is' preferably threade members are e ends of the laced on the y this means against t tubes by means of'the nuts: 7

the ties are not depended upon to hold the rails in parallelism, and if desired, little or no. securing means need be provided for'secure ing the rails to the ties. struction'shown in Figure 1, the fish plates 8 together at their ends,

are made Independent of the clamps 44.

In the form of construction shown in Figure 2, the fish plates 8- are made integral with the. clamping members 4'-4,, and t e menibers 4 are provided'with downwardly projecti ears 9 throu h which the bolt 10 1s Fig'uite'3. The joint12-of Fig. 3 is secured v bymeans-,of the independent fish jplates,

the right is secured by clamps.

(Figure 3) which strap is secured by-means of the bolts 15.. "'In. the enlarged detail construction as shown in Figures 4, 5 and 6, the

indicated in Figure 3. 65 f In orderto hold the two sides of the track n the form of con-. 80

ate portions 8 are s ecured by means of the bolts 11 as shown in rod construction is slightly changed in that the rod'is provided at one end with-anintegral head 7 instead of having nuts at both ends asin the construction shown in Figure 1'.

' The: construction of the tie is shown in Figures 7,8, Qand 1 0, and as here shown the tie comprises a pressed steel bottom sheet 16.

Figure l liois amenlarged' detail section through amodified form of track constructionf Referring first to the form of deviceas shown in cross section in Figure 1, 1 1 are *the nails, 22 are the stifiening sections be neath and parallel to the rails 1- 1, whichsections are preferably in the form of abulb,

provided with up-turned edges 17 The bottom sheet is corrugated as shown at 18 in order to give a better grip upon the road bed, and the ends are curved down as shown at 19 for a similar purpose. As indicated in Figure 9, the ends of the'tie are flared, and the up-turned edges 17 taper down to the bottom sheet at such end portions, giving the tie the contour shown in side elevation 1n Figure 7. In order to provide a seat for the rail, thelips 20 are pressed down from the up-turned edges 17, thus providing for the seatin of the rail in the u or surface of the the liners 23 (Fig. 10) are inserted beneath the lips 20. It will be observed that by this arrangement the rail is not only prevented from moving longitudinally with res set to the tie, but is secured against vertica movement by virtue of the engagement of the clamps 21 with the lips 20.

In Figure 11 a modified form of track construction is shown. As here shown, the rail 1 and stiffening sections 2 are spaced apart by means of the eye-bar 24, and all the parts are clamped together by means of the cli members 25, and transverse bolts 26. This arrangement also prevents longitudinal movement of the rail with respect to the ties, as the end of the member 24 and the ends of the clip 25 bear against the sides of the ties and thus hold the parts in position.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent is the following:

1. The combination with rails, parallel flanged stifliening sections therebeneath; and

interposed ties, of spacing and securing means comprising pairs of opposing clamps between and engaging the ties, each clamp adapted to flt one side of a rail flange and one side of a stiffening section flange and means for securing the clamps against the said flanges. I

2.. The combination with a rail, flanged stiflening sections beneath and paralleling the rail, and interposed ties, of means for securing the rail to the section comprising two opposing clamps each having means for en gaging the flanges of therail and stiffening section and each provided with a web inturned to meet the other beneath the web of the rail, and means for securing the inturned webs together.

gether and for holding The combination with rails, andparallel flanged stiffening sections therebeneath, of spacing and securing means comprising a pair of opposing clamps adjacent the ends of the rails and each adapted to lit one side of a rail flange and web and one side of a sti'llening section flange and web, bolts for securing the clamps against the said flanges and webs, and other bolts through the webs of the still ening section and the clamps for securing the parts in position.

4. The combination with atraclr com rising a pair of parallel rails, of a parallel sti lening section beneath each rail, interposed ties, spacing members between the rails and stiffening sections for securing such parts together, and means extending transversely across the track between the spacing members for holding them in fixed relative position.

5. The combination with a track comprising a pair of parallel rails, of a parallel stil'l'ening section beneath each rail, interposed ties, spacing members between the rails and stillening sections for securing such parts together, tube members extending between the spacing members on opposite sides of the track, and bolts extending through the tubes and the spacing members for holding such spacing members against the ends of the tubes.
